Glutaraldehyde manufacturers

Buyers must prioritize the concentration level, typically ranging from 2% (medical grade) to 50% (industrial grade). It is essential to verify the pH value, as Glutaraldehyde is most stable at a slightly acidic pH (3.0–4.5) but most biocidally active when activated to an alkaline state (pH 7.5–8.5). Additionally, ensure the methanol content is minimized to prevent polymerization and maintain product purity.

As a hazardous chemical, Glutaraldehyde must have a valid Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) compliant with GHS standards. For medical sterilization, look for ISO 13485 or CE marking. For water treatment or oil/gas applications, ensure the supplier complies with REACH (EU) or EPA (USA) registrations to avoid customs seizures.

Glutaraldehyde is sensitive to temperature and light. Professional suppliers should provide stability testing reports. High-quality Glutaraldehyde should have a shelf life of 12 to 24 months when stored in cool, ventilated areas (below 25°C) and kept in opaque, UV-resistant HDPE containers. Ask the supplier about their stabilizer additives which prevent the solution from turning yellow or polymerizing.

The 50% industrial grade is primarily used for water treatment, paper pulp processing, and oilfield biocides. The 25% grade is common in leather tanning and photography. The 2% to 5% activated solutions are strictly for medical instrument disinfection and healthcare sanitation. Ensure your supplier understands the specific application to provide the correct formulation and packaging.

Glutaraldehyde is classified as a Class 8 Corrosive Substance (UN 3265 or UN 1909). It requires UN-certified packaging (usually blue HDPE drums or IBC tanks) with clear hazardous material labeling. You must use a freight forwarder experienced in DG (Dangerous Goods) cargo and ensure the Dangerous Goods Declaration is accurately filed to prevent heavy fines or port rejection.

Always request a Pre-Shipment Inspection (PSI) conducted by third parties like SGS or Intertek to verify the concentration and purity via titration analysis. Use secure payment methods and prioritize Gold Suppliers on Made-in-China.com who offer Audit Reports and have a proven track record of exporting hazardous chemicals to your specific region.

Prices for Glutaraldehyde are heavily influenced by the cost of raw materials like Vinyl Ethyl Ether and Acrolein. Negotiate based on annual volume contracts rather than spot buys to secure stable pricing. Ask for tiered pricing (e.g., 5-ton vs. 20-ton FCL) and clarify if the quoted price includes specialized DG palletization and bracing required for sea freight.

Many countries have strict biocidal product regulations (like BPR in Europe). Ensure the supplier is listed on the Article 95 list if shipping to the EU. Failure to align with import permits or local chemical inventory listings (like TSCA in the US or IECSC in China) can lead to the permanent destruction of the cargo at the border.
